Seven problems related to brakes failed have been reported for the 2006 BMW X5. The most recently reported issues are listed below.
BMW X5 brake booster failed. I was driving in town and attempted to stop and noticed that the truck needed more brake pedal pressure the longer I applied the brakes. The pedal began to rise and the truck would begin to creep forward unless more pressure was applied to the pedal. I drove to the BMW dealership to have a recall performed on the passenger seat occupancy mat. During that visit I informed the service writer of the brake issue and asked if it would be corrected under a recall as well. I was told that my vehicle was not covered by any other recalls. I researched it and found that some BMW X5's we're experiencing some issues with the brakes and were being recalled but not my vehicle. I ordered all necessary parts and replaced them myself. Which consisted of a new updated pump, all updated oem lines with check valves and a new trw oem brake booster. Research shows that engine oil vapor travels into the lines and up to the booster which caused the rubber diaphram to fail in the brake booster. These are all the same parts mentioned in the recalls on other BMW X5's covered by the recalls.
Brake booster failed while stopped without any warning lights.

This is a serious problem , this is not a tail light not working , this is putting people lives in danger. The repair cost is $2300.

The brakes failed while I was driving to work. I stepped on the brakes to stop from approximately 30mph and the vehicle did not slow down or come to a stop. I had to steer onto the median to avoid hitting the vehicle in front of me. Mechanic said the booster needs to be replaced. No warnings displayed in dashboard. Extremely dangerous and I'm lucky to have avoided a more serious accident. Someone could have been seriously hurt given the size of this vehicle.
